     Aluminum is an abundant metal, with many uses. It is produced in an ore called bauxite. Bauxite looks like clay, but it contains many substances including aluminum. To be useful the aluminum must be extracted from the bauxite and other substances.
     The bauxite is placed into pressurized tanks which causes the other substances to form a mass. This mass is filtered out leaving a liquid. The liquid is put through many more processes, unitl it yields a chemical. The white, powdery cemical is alumina, which is a mixture of oxygen and aluminum.
     Using electricity, workmen separate the oxygen from the aluminum. After the oxygen is extracted all that is left is a lusterous, silvery metal. The metal is aluminum, which has many, many forms.
